• Multiple Jira instances on a single Tomcat 6 server?

  - by davidhayes

  I have a feeling this is a stupid question but I can't find the answer anywhere... I need to deploy 2 Jira instances on asingle Tomcat server, I can't figure out how to pass in the jira.home property The documentation says I need to:- Add a web context property called 'jira.home' — this property is set in different files depending on your application server. For example, for Tomcat (and therefore for JIRA Standalone), you will need to configure the server.xml file. For other application servers you may need to configure the web.xml file, or set 'Context parameter' options on the deployment UI of the application server, etc. Note that If you have specified a JIRA home in jira-application.properties (ie. the recommended method), it will override your web context property. I was hoping something like this would work. <Context jira.home="d:/jira/data" path="" docBase="D:\Jira\atlassian-jira-enterprise-4.1\dist-tomcat\tomcat-6\atlassian-jira-4.1.war" debug="0"> <Resource name="jdbc/JiraDS" auth="Container" type="javax.sql.DataSource" username="sa" password="*****" driverClassName="net.sourceforge.jtds.jdbc.Driver" url="jdbc:jtds:sqlserver://*****:1433/jira41_519;user=****;password=****" /> <Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction" factory="org.objectweb.jotm.UserTransactionFactory" jotm.timeout="60"/> <Manager pathname=""/> </Context> Any ideas??

• VB.Net Custom Object Master-Detail Data Binding

  - by clawson

  Since beginning to use VB.Net some years ago I have become slowly familiar with using the data binding features of .Net, however I often find my self bewildered by it's behavior and instead of discover the correct way it should work I find some dirty work around to suit my needs and continue on. Needless to say my problems continue to arise. I am using Custom Objects as the Data Sources for by controls and often entire forms. I find it frustrating to separate business logic and the graphical interface. (That could be a new question entirely.) So for a lot of objects I generate a form which has the DataBindingSource for the object. When I create each from using the New Constructor I explicitly pass to it the object to which it should be bound, and then set this passed object as the DataSource of the BindingSource. (That's a mouthful!) Now the Master object (say, bound to each form) often contains a List of objects which I like to have displayed in a DataGridView. I (sometimes) create and modify these child objects in their own form (again creating a databind the same way as the master form) but when I add them to the List in the master object the DataGridView won't update with the new items. So my question really has a few layers: How can I easily/efficiently/correctly update this DataGridView with the list of Detail objects when I add them to the list of the Master object. Is this approach to DataBinding good/viable. What's the best way to separate business logic from graphical interface. Thanks for the help!

• LINQ compiled query DataBind issue

  - by Brian

  Hello All, I have a pretty extensive reporting page that uses LINQ. There is one main function that returns an IQueryable object. I then further filter / aggregate the returned query depending on the report the user needs. I changed this function to a compiled query, it worked great, and the speed increase was astonishing. The only problem comes when i want to databind the results. I am databinding to a standard asp.net GridView and it works fine, no problems. I am also databinding to an asp.net chart control, this is where my page is throwing an error. this works well: GridView gv = new GridView(); gv.DataSource = gridSource; But this does not: Series s1 = new Series("Series One"); s1.Points.DataBindXY(gridSource, "Month", gridSource, "Success"); The error i receive is this: System.NotSupportedException Specified method is not supported When i look into my gridSource var at run time i see this using a typical linq query: SELECT [t33].[value2] AS [Year], [t33].[value22] AS [Month], [t33].[value3] AS [Calls]...... I see this after i change the query to compiled: {System.Linq.OrderedEnumerable<<>f__AnonymousType15<string,int,int,int,int,int,int,int>,string>} This is obviously the reason why the databindxy is no longer working, but i am not sure how to get around it. Any help would be appreciated! Thanks

• Adding a Combobox to a DataGrid in Silverlight

  - by bplus

  I can add a Combobox to a DataGrid using following xmal: <local:DataGridTemplateColumn Header="SomeHeader" Width="106" HeaderStyle="{StaticResource headerAlignRightStyle}" CellStyle="{StaticResource cellAlignRightStyle}"> <local:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding SomeProp}" Margin="4"/> </DataTemplate> </local:DataGridTemplateColumn.CellTemplate> <local:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ComboBox x:Name="SomeCombo" SelectionChanged="SomeCombo_SelectionChanged" ItemsSource="{Binding SomeList}" DisplayMemberPath="Name" /> </DataTemplate> </local:DataGridTemplateColumn.CellEditingTemplate> </local:DataGridTemplateColumn> However what I can't figure out is a sensible way to get the row that was combox is bound to. i.e. when handling the combobox SelectionChanged event I have no way of knowing what what row the combobox belongs to. Particularly I don't know what object in the DataGrid datasource that the combobox is refering to. Any help would be much appreciated.

• uitableview reloadData issue

  - by CocoaNewBee

  I've been debugging my iphone app and found something interesting. I have a UIViewControllers with TabBarcontroller( 6 tabs). each tab is a UIViewController and it has a UITtableview. The viewDidLoad works and brings the initial data. On of the UITableView has a search bar. After the user touchs presses search some magic happens and I get an array with data. I cant see the new data in the tableview and the [tableView reloadData] has no effect outside viewDidLoad (first time). I can see the array holding the data and the dataSource is set to self. Yet, no displaying of data! so I 've tried [self.tableView reloadData] & [self.tableView setNeedsDisplay] Funny enough, the new data is not being displayed. However if I move the table up or down the cellForRowAtIndexPath is being fired and the first row shows data. can anyone shed some light on this mystery??? if there a [self.view refreshscreen] ??

• DataGrid finding a control

  - by nat

  HI I have a DataGrid (yes would be nicer if it was a gridview but nothing i can do about that) in the itemDataBound event i am adding a hidden field into the first cell of each row I am setting its ID based on something, and then saving its clientID in a List for later attempts to get the value from it but try as i might i cant find anything with findcontrol have tried here is the itemdatabound bit foreach(page in datasource){ HiddenField hidOrder = new HiddenField(); hidOrder.ID = "order_" + page.Id.ToString(); hidOrder.Value = page.Ordering.ToString(); e.Item.Cells[0].Controls.Add(hidOrder); idList.Add(hidOrder.ClientID); } then this is a button click event.. int numRows = FrontEndDataGrid.Items.Count; for (int i = 0; i < numRows; i++){ foreach(string hidID in idList){ HiddenField hf = FrontEndDataGrid.Items[i].FindControl(hidID) as HiddenField; //ssadly this never finds anything //have also tried looping around the cells for each 'row' - no luck there either } } any ideas? thanks nat

• SQL Server 2005 Reporting Services and the Report Viewer

  - by Kendra

  I am having an issue embedding my report into an aspx page. Here's my setup: 1 Server running SQL Server 2005 and SQL Server 2005 Reporting Services 1 Workstation running XP and VS 2005 The server is not on a domain. Reporting Services is a default installation. I have one report called TestMe in a folder called TestReports using a shared datasource. If I view the report in Report Manager, it renders fine. If I view the report using the http ://myserver/reportserver url it renders fine. If I view the report using the http ://myserver/reportserver?/TestReports/TestMe it renders fine. If I try to view the report using http ://myserver/reportserver/TestReports/TestMe, it just goes to the folder navigation page of the home directory. My web application is impersonating somebody specific to get around the server not being on a domain. When I call the report from the report viewer using http ://myserver/reportserver as the server and /TestReports/TestMe as the path I get this error: For security reasons DTD is prohibited in this XML document. To enable DTD processing set the ProhibitDtd property on XmlReaderSettings to false and pass the settings into XmlReader.Create method. When I change the server to http ://myserver/reportserver? I get this error when I run the report: Client found response content type of '', but expected 'text/xml'. The request failed with an empty response. I have been searching for a while and haven't found anything that fixes my issue. Please let me know if there is more information needed. Thanks in advance, Kendra

• UIScrollview calling superviews layoutSubviews when scrolling?

  - by marchinram

  Hello, I added a UITableView as a subview to a custom UIView class I'm working on. However I noticed that whenever I scroll the table it calls my classes layoutSubviews. I'm pretty sure its the UIScrollview that the table is inheriting from which is actually doing this but wanted to know if there is a way to disable this functionality and if not why is it happening? I don't understand why when you scroll a scrollview it needs its superview to layout its subviews. Code: @implementation CustomView - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { self.clipsToBounds = YES; UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 15.0, 436.0, 132.0) style:UITableViewStylePlain]; tableView.dataSource = self; tableView.delegate = self; tableView.separatorStyle = UITableViewCellSeparatorStyleNone; tableView.backgroundColor = [UIColor clearColor]; tableView.showsVerticalScrollIndicator = NO; tableView.contentInset = UIEdgeInsetsMake(kRowHeight, 0.0, kRowHeight, 0.0); tableView.tag = componentIndex; [self addSubview:tableView]; [tableView release]; } return self; } - (void)layoutSubviews { // This is called everytime I scroll the tableview } @end

• What is the Best way to databind an ASP.NET TreeView for table with many to many parent child relati

  - by Matt W

  I've got a table which has the usual ParentID, ChildID as it's first two columns in a self-referencing tree data structure. My issue is that when I pull this out and use the following code: DataSet set = DA.GetNewCategories(); set.Relations.Add( new DataRelation("parentChildCategories", set.Tables[0].Columns["CategoryParentID"], set.Tables[0].Columns["CategoryID"]) ); StringBuilder buildXml = new StringBuilder(); StringWriter writer = new StringWriter(buildXml); set.WriteXml(writer); TreeView2.DataSource = new HierarchicalDataSet(set, "CategoryID", "CategoryParentID"); TreeView2.DataBind(); I get the error: These columns don't currently have unique values I believe this is because my data has children with multiple parent nodes. This is fine for my application - I don't mind if one row of data is rendered in multiple nodes of my TreeView. Could someone shed light on this please? It doesn't seem unreasonable to have a DataSet render XML which has nodes appearing in multiple places, but I can't figure out how to do it. Thanks, Matt.

• Getting values from DataGridView back to XDocument (using LINQ-to-XML)

  - by Pretzel

  Learning LINQ has been a lot of fun so far, but despite reading a couple books and a bunch of online resources on the topic, I still feel like a total n00b. Recently, I just learned that if my query returns an Anonymous type, the DataGridView I'm populating will be ReadOnly (because, apparently Anonymous types are ReadOnly.) Right now, I'm trying to figure out the easiest way to: Get a subset of data from an XML file into a DataGridView, Allow the user to edit said data, Stick the changed data back into the XML file. So far I have Steps 1 and 2 figured out: public class Container { public string Id { get; set; } public string Barcode { get; set; } public float Quantity { get; set; } } // For use with the Distinct() operator public class ContainerComparer : IEqualityComparer<Container> { public bool Equals(Container x, Container y) { return x.Id == y.Id; } public int GetHashCode(Container obj) { return obj.Id.GetHashCode(); } } var barcodes = (from src in xmldoc.Descendants("Container") where src.Descendants().Count() > 0 select new Container { Id = (string)src.Element("Id"), Barcode = (string)src.Element("Barcode"), Quantity = float.Parse((string)src.Element("Quantity").Attribute("value")) }).Distinct(new ContainerComparer()); dataGridView1.DataSource = barcodes.ToList(); This works great at getting the data I want from the XML into the DataGridView so that the user has a way to manipulate the values. Upon doing a Step-thru trace of my code, I'm finding that the changes to the values made in DataGridView are not bound to the XDocument object and as such, do not propagate back. How do we take care of Step 3? (getting the data back to the XML) Is it possible to Bind the XML directly to the DataGridView? Or do I have to write another LINQ statement to get the data from the DGV back to the XDocument? Suggstions?

• Updating Database from DataSet

  - by clawson

  I am having trouble updating my Database from my code using a DataSet. I'm using SQL Server 2008 and Visual Studio 2008. Here is what I've done so far. I have created a table in SQL Server called MyTable which has two columns: id nchar(10), and name nchar(50). I have then created a datasource in my VB.net project that consists of this table using the dataset wizard and called this dataset MyDataSet. I run the following code on a button click: Try Dim myDataSet As New MyDataSet Dim newRow As MyDataSet.MyTableRow = myDataSet.MyTable.NewMyTableRow newRow.id = "1" newRow.name = "Alpha" myDataSet.MyTable.AddMyTableRow(newRow) myDataSet.AcceptChanges() Catch ex As Exception MsgBox(ex.Message) End Try when I run this and check the rows in SQL Server it returns 0 rows What have I missed? How can I add these rows / save changes in a dataset to the database? I have seen other examples that use a TableAdapter but I don't think I want to do this, I think I should be able to achieve this just using a DataSet. Am I mistaken? Help is greatly appreciated!

• "Illegal characters in path." Visual Studio WinForm Design View

  - by jacksonakj

  I am putting together a lightweight MVP pattern for a WinForms project. Everything compiles and runs fine. However when I attempt to open the WinForm in design mode in Visual Studio I get a "Illegal characters in path" error. My WinForm is using generics and inheriting from a base Form class.

• Passing a LINQ DataRow Reference in a GridView's ItemTemplate

  - by Bob Kaufman

  Given the following GridView: <asp:GridView runat="server" ID="GridView1" AutoGenerateColumns="false" DataKeyNames="UniqueID" OnSelectedIndexChanging="GridView1_SelectedIndexChanging" > <Columns> <asp:BoundField HeaderText="Remarks" DataField="Remarks" /> <asp:TemplateField HeaderText="Listing"> <ItemTemplate> <%# ShowListingTitle( ( ( System.Data.DataRowView ) ( Container.DataItem ) ).Row ) %> </ItemTemplate> </asp:TemplateField> <asp:BoundField HeaderText="Amount" DataField="Amount" DataFormatString="{0:C}" /> </Columns> </asp:GridView> which refers to the following code-behind method: protected String ShowListingTitle( DataRow row ) { Listing listing = ( Listing ) row; return NicelyFormattedString( listing.field1, listing.field2, ... ); } The cast from DataRow to Listing is failing (cannot convert from DataRow to Listing) I'm certain the problem lies in what I'm passing from within the ItemTemplate, which is simply not the right reference to the current record from the LINQ to SQL data set that I've created, which looks like this: private void PopulateGrid() { using ( MyDataContext context = new MyDataContext() ) { IQueryable < Listing > listings = from l in context.Listings where l.AccountID == myAccountID select l; GridView1.DataSource = listings; GridView1.DataBind(); } }

• get column names from a table where one of the column name is a key word.

  - by syedsaleemss

  Im using c# .net windows form application. I have created a database which has many tables. In one of the tables I have entered data. In this table I have 4 columns named key, name,age,value. Here the name "key" of the first column is a key word. Now I am trying to get these column names into a combo box. I am unable to get the name "key". It works for "key" when I use this code: private void comboseccolumn_SelectedIndexChanged(object sender, EventArgs e) { string dbname = combodatabase.SelectedItem.ToString(); string path = @"Data Source=" + textBox1.Text + ";Initial Catalog=" + dbname + ";Integrated Security=SSPI"; //string path=@"Data Source=SYED-PC\SQLEXPRESS;Initial Catalog=resources;Integrated Security=SSPI"; SqlConnection con = new SqlConnection(path); string tablename = comboBox2.SelectedItem.ToString(); //string query= "Select * from" +tablename+; //SqlDataAdapter adp = new SqlDataAdapter(" Select [Key] ,value from " + tablename, con); SqlDataAdapter adp = new SqlDataAdapter(" Select [" + combofirstcolumn.SelectedItem.ToString() + "]," + comboseccolumn.SelectedItem.ToString() + "\t from " + tablename, con); DataTable dt = new DataTable(); adp.Fill(dt); dataGridView1.DataSource = dt; } This is beacuse I am using "[" in the select query. But it wont work for non keys. Or if I remove the "[" it is not working for key . Please suggest me so that I can get both key as well as nonkey column names.

Right now, I'm trying to figure out the easiest way to: Get a subset of data from an XML file into a DataGridView, Allow the user to edit said data, Stick the changed data back into the XML file. So far I have Steps 1 and 2 figured out: public class Container { public string Id { get; set; } public string Barcode { get; set; } public float Quantity { get; set; } } // For use with the Distinct() operator public class ContainerComparer : IEqualityComparer<Container> { public bool Equals(Container x, Container y) { return x.Id == y.Id; } public int GetHashCode(Container obj) { return obj.Id.GetHashCode(); } } var barcodes = (from src in xmldoc.Descendants("Container") where src.Descendants().Count() > 0 select new Container { Id = (string)src.Element("Id"), Barcode = (string)src.Element("Barcode"), Quantity = float.Parse((string)src.Element("Quantity").Attribute("value")) }).Distinct(new ContainerComparer()); dataGridView1.DataSource = barcodes.ToList(); This works great at getting the data I want from the XML into the DataGridView so that the user has a way to manipulate the values. Upon doing a Step-thru trace of my code, I'm finding that the changes to the values made in DataGridView are not bound to the XDocument object and as such, do not propagate back. How do we take care of Step 3? (getting the data back to the XML) Is it possible to Bind the XML directly to the DataGridView? Or do I have to write another LINQ statement to get the data from the DGV back to the XDocument? Suggstions?

• VS2008 adding SQL Server Database (SQL Server 2008 Mgmt Studio) not working

  - by Kahn

  I'm trying to practice using the ASP.Net MVC at home, but I ran into an impossible problem. I cannot open a connection to SQL Server 2008, I get this error: "Connections to SQL Server files (*.mdf) require SQL Server Express 2005 to function properly. ..." I've googled around for numerous responses, none of them either working or addressing this issue. I'm running Vista 32bit, my SQL Server 2008 Mgmt Studio is also 32bit, I have SP1 installed both on VS2008 Professional, as well as the SQL Server. I changed the machine.config connectionStrings from ./SQLExpress to my SQL Server 2008 name. Now if I connect manually through web.config, in an asp:datasource or code-behind, everything works fine. But for some reason trying to add a DB Connection directly like this always gets the error. This is pretty fatal, since I can't rightly do much unless I can use LINQ to SQL with my MVC test project, and this is the only way I know how. Worked fine in school and work, but not at home. Installing SQL Server Express 2005, as some have suggested, is not an option. Obviously it HAS to work with SQL Server 2008. Thanks in advance.

• Excel Reader ASP.NET

  - by user304429

  I declared a DataGrid in a ASP.NET View and I'd like to generate some C# code to populate said DataGrid with an Excel spreadsheet (.xlsx). Here's the code I have: <asp:DataGrid id="DataGrid1" runat="server"/> <script language="C#" runat="server"> protected void Page_Load(object sender, EventArgs e) { string connString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\FileName.xlsx;Extended Properties=""Excel 12.0;HDR=YES;"""; // Create the connection object OleDbConnection oledbConn = new OleDbConnection(connString); try { // Open connection oledbConn.Open(); // Create OleDbCommand object and select data from worksheet Sheet1 OleDbCommand cmd = new OleDbCommand("SELECT * FROM [sheetname$]", oledbConn); // Create new OleDbDataAdapter OleDbDataAdapter oleda = new OleDbDataAdapter(); oleda.SelectCommand = cmd; // Create a DataSet which will hold the data extracted from the worksheet. DataSet ds = new DataSet(); // Fill the DataSet from the data extracted from the worksheet. oleda.Fill(ds, "Something"); // Bind the data to the GridView DataGrid1.DataSource = ds.Tables[0].DefaultView; DataGrid1.DataBind(); } catch { } finally { // Close connection oledbConn.Close(); } } </script> When I run the website, nothing really happens. What gives?

• How to get NSFormatter subclass to work with NSTableColumn sort key and selector?

  - by Andrew

  My setup: I have a sqlite database from which I populate a NSMutableArray of NSDictionary objects this is the DataSource for my NSTableView. One of the columns holds "time", the time is a float that holds seconds. I would like to display the values in this column as minutes:seconds. For instance my data would be 123.4329387 I want to display 2:03 which I have no problem doing with a subclass of NSFormatter (or NSNumberFormatter) applied to my NSTextField in the column. I have sorting set up by using the Table Column Attributes in IB, I just have the sort key set to "time" and the selector set to "compare:" which works fine without the formatter. Currently this gives me something like this when I sort (descending) 1:37, 1:31, 0:10, 0:10, 0:09, 1:30, 1:30, 1:26, 0:09 and similar nonsense, it looks like something is going on but it's definitely not sorted. How do I get the sort to look at the underlying data instead of the formatted value? Alternately, how do I specify a custom sort method and where do I put the code for said method? I have searched around quite a bit and have not found anything to help me out with this problem, any help with this is most appreciated.

• Custom Repeater with hiractial Databinding

  - by Dooie

  Im using a Custom NestedRepeater Control for ASP.NET which can be found on code project The source is in c# which i have converted to vb and plugged into my solution, so far so good. The problem, im having is databinding to the repeater, my code behind looks like this... '' get all pages Dim navPages As DataSet = Navigation.getMenuStructure() navPages.Relations.Add(navPages.Tables(0).Columns("ID"), navPages.Tables(0).Columns("ParentID")) NestedRepeaterNavigation.RelationName = RelationName NestedRepeaterNavigation.DataSource = navPages NestedRepeaterNavigation.RowFilterTop = "ParentID is null" NestedRepeaterNavigation.DataBind() Then in the item template of my custom repeater im trying the following... <ItemTemplate> <img src="/pix.gif" height="10" width="<%#(Container.Depth * 10)%>"> <%# (Container.DataItem as DataRow)["DESCRIPTION"]%> <%# (Container.NbChildren != 0 ? "<small><i>(" + Container.NbChildren.ToString() +")</i></small>" "") %><small><i></i></small> </ItemTemplate> The databinding falls over; firstly that 'as DataRow' says it was expecting an ')'. And secondly that '!=' identifier expected. Is this due to the translation from c#, should the databinding be different?
